EN 17333-3:2020 - Characterisation of One Component Foam (Part 3: Application)

Overview

EN 17333-3:2020 is a CEN European standard that defines test methods to evaluate the application properties of one component foams (OCFs) dispensed from single pressurized foam containers. It covers moisture-curing, self‑curing activatable and water‑drying foams supplied in aerosol cans or gun cans. The standard describes how to determine practical performance attributes that affect on‑site use and quality control.

Keywords: EN 17333-3:2020, one component foam, OCF, cutting time, tack free time, sagging, test methods, moisture curing, pressurized foam containers

Key topics and requirements

• Scope and definitions: terms such as one component foam (OCF), pressurised foam container, cutting time, tack free time, and sagging are defined consistently with EN 923 and related norms.
• Test environment and sampling:
  • Conditioning of test containers at test temperature for at least 24 h.
  • Typical test conditions specified: (23 ± 2) °C and (50 ± 5) % RH (other conditions may be reported).
  • Preparation steps (e.g., shake container, discard first dose) are required for repeatable results.
• Three standardized application tests:
  • Method 1 - Cutting time: Dispense beads on a horizontal surface and determine time until a knife cuts without sticking or deforming the bead; result reported to nearest full 5 minutes.
  • Method 2 - Tack free time: Touch the bead surface periodically with a clean rod/adapter tube until no adhesion is detected; result in minutes to nearest full minute.
  • Method 3 - Sagging: Spray foam into vertical joints of increasing width to evaluate slip/flow and establish maximum usable joint width at given canister and ambient temperatures.
• Reporting: test reports must include reference to the standard, laboratory and sample identification, test conditions, any deviations, and observations.

Practical applications and users

• Manufacturers and R&D teams: optimise formulations, nozzle adapters, and dispensing systems based on cutting time, tack free time and sagging behavior.
• Quality control laboratories: verify batch conformity and stability claims under standardized conditions.
• Product specifiers, procurement and certification bodies: compare OCF products using consistent, repeatable metrics for performance and usability.
• Construction and insulation contractors: understand product suitability for vertical joints, cure timing and handling windows to plan installations.

Related standards

• EN 17333 series: Part 1 (Foam yield characteristics), Part 2 (Expansion characteristics), Part 4 (Mechanical strength), Part 5 (Insulation).
• Normative references cited: EN 923 (terms and definitions), EN 14847 and EN 15006 (pressurised container dimensions).

Note: EN 17333-3:2020 does not address all safety concerns. Users must establish appropriate health, safety and regulatory compliance before use.
